Vehicle systems for use in cosmetic compositions

ABSTRACT

Disclosed is a unique vehicle system which provides a desirable rheology to products formulated therewith, enhanced dispersion of actives therein, and improved deposition of actives therefrom. This vehicle system comprises a primary thickening agent which is a nonionic long chain alkylated water-soluble polymer, and a secondary thickening agent which is a water-soluble surfactant, dispersed in a compatible solvent. Optionally, a rheological aid, which is a chelating agent may be included in the vehicle system. Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be included in the vehicle system. These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the hair or skin. The vehicle systems are particularly useful in hair care compositions, especially rinse-off hair conditioning compositions, because they effectively deliver the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.

TECHNICAL FIELD

This application is a continuation-in-part of U.S. application Ser. No.390,268, Bolich et al., filed Aug. 7, 1989, now abandoned.

The present invention relates to novel vehicle systems, and cosmeticcompositions formulated therewith, based on particular nonionic longchain alkylated water-soluble polymer derivatives and water-solublesurfactants at certain critical levels dispersed in a compatiblesolvent. A particularly useful application of the present invention isin hair care compositions, especially rinse-off hair conditioningcompositions.

BACKGROUND OF THE INVENTION

Typical hair conditioning products have a particular thick rheology thatis desirable for such products. These products are based on thecombination of a surfactant, which is generally a quaternary ammoniumcompound, and a fatty alcohol. This combination results in a gel-networkstructure which provides the composition with a thick rheology. However,while such compositions deliver conditioning benefits to the hair, suchcompositions also deposit in hair making hair look and feel dirty.

Alternative thickening systems have been used in hair care compositions,but none have been found to date which provide this same desirablerheology. Though hair care products thickened with polymer thickenerscan be made to have a thick rheology, these products generally arecharacterized by an undesirable "slimy"feel and do not hold their pouredshape.

Nonionic water-soluble cellulose ethers are employed in a variety ofapplications, including hair care compositions. Widely used,commercially-available nonionic cellulose ethers include methylcellulose, hydroxy propyl methyl cellulose, hydroxyethyl cellulose,hydroxypropyl cellulose and ethyl hydroxyethyl cellulose.

Better thickening efficiency is realized with higher molecular weightcellulose ethers. However, production of such materials is difficult andexpensive. Though crosslinking of these polymers is an alternative meansto achieve high viscosity solutions, good crosslinking techniques arenot known. Of course, high concentrations of polymers will also providehigh viscosity but such an approach is inefficient and impractical,particularly due to the high expense involved. Furthermore, use ofhighly crosslinked polymers or high levels of polymeric thickeners mayresult in a vehicle system that is too elastic for the present uses.

Alternative water-soluble polymeric thickeners sometimes used to thickenhair care compositions are natural polysaccharides such as guar gum,xanthan gum and locust bean gum.

A number of references teach the use of nonionic cellulose ethers andwater-soluble gums for thickening hair care compositions. See forexample, U.S. Pat. No. 4,577,928, Glover, issued Dec. 10, 1985, teachinga hair conditioner comprising a suspension system which consists of oneof glucan gum, guar gum, and hydroxyethylcellulose; and U.S. Pat. No.4,581,230, Grollier et al;, issued Apr. 8, 1986, which teaches cosmeticcompositions for treating hair which comprise as thickening agentshydroxyethylcellulose, or water-soluble vegetable thickening agents,such as guar gum. Japanese Patent Publication 61-053211, published Mar.7, 1986, discloses a hair colorant containing an aromatic alcohol,xanthan gum, and hydroxyethylcellulose.

Certain cellulose ethers have been disclosed in U.S. Pat. No. 4,228,277,Landoll, issued Oct. 14, 1980, which are relatively low molecular weightbut which are capable of producing highly viscous aqueous solutions inpractical concentrations. These materials are nonionic cellulose ethershaving a sufficient degree of nonionic substitution selected from thegroup consisting of methyl, hydroxyethyl, and hydroxypropyl to causethem to be water-soluble and which are further substituted with ahydrocarbon radical having from about 10 to 24 carbon atoms in an amountbetween about 0.2 weight percent and the amount which renders saidcellulose ether less than 1%, by weight, soluble in water. The celluloseether to be modified is preferably one of low to medium molecularweight; i.e., less than about 800,000 and preferably between about20,000 and 700,000 (about 75 to 2500 D.P.).

These modified cellulose ethers have been disclosed for use in a varietyof composition types. Landoll ('277) teaches the use of these materialsin shampoo formulations. Hercules trade literature teaches the use ofthese materials in shampoos, liquid soaps, and lotions. U.S. Pat. No.4,683,004, Goddard, issued July 28, 1987, discloses the use of thesematerials in mousse compositions for the hair. U.S. Pat. No. 4,485,089,Leipold, issued Nov. 27, 1984, teaches dentifrice compositionscontaining these materials.

These materials have now been found to provide a rheology very much likethe desirable gel-network structure of typical hair conditioners(without the slimy feel associated with most polymeric thickeners), whenthey are combined with surfactants at certain critical levels.

Hence, it is an object of the present invention to provide a vehiclesystem for hair care and other cosmetic compositions which provides agel-network-like structure to the composition but which is not based ona typical quaternary ammonium compound/fatty alcohol gel-networkthickening system.

It is also an object of the present invention to provide a vehiclesystem for hair care and other cosmetic compositions which allows fordispersion of a wide variety of active hair or skin care componentstherein.

It is also an object of the present invention to provide a vehiclesystem for hair care and other cosmetic compositions which will maximizedeposition of the active hair or skin care component contained thereinonto the hair or skin while minimizing deposition of the vehicle systemcomponents.

These other objects will become readily apparent from the detaileddescription which follows.

SUMMARY OF THE INVENTION

The present invention relates to unique vehicle systems for use incosmetic compositions which are polymer-based but which provide arheology to the cosmetic compositions which mimics gel-network systems.These vehicle systems are based on a two-component thickening system.More specifically, the cosmetic compositions of the present inventioncomprise:

(a) from about 80% to about 100% preferably from about 80% to about99.9%, of a vehicle system which comprises:

(A) from about 0.1% to about 10.0% by weight of the cosmetic compositionof a hydrophobically modified nonionic water-soluble polymer whichcomprises a water-soluble polymer backbone and hydrophobic groupsselected from the group consisting of C₈ -C₂₂ alkyl, arylalkyl,alkylaryl groups and mixtures thereof; wherein the ratio of hydrophilicportion to hydrophobic portion of the polymer is from about 10:1 toabout 1000:1; preferably the hydrophobically modified nonionicwater-soluble polymer comprises a nonionic cellulose ether having asufficient degree of nonionic substitution selected from the groupconsisting of methyl, hydroxyethyl, and hydroxypropyl to cause it to bewater-soluble and being further substituted with a long chain alkylradical having 10 to 22 carbon atoms in an amount between about 0.2weight percent and the amount which renders said cellulose ether lessthan 1% by weight soluble in water;

The vehicle system provides a rheology to the cosmetic compositionsformulated therewith, that is preferably characterized by a shear stressof from 0 to about 50 pascal over a shear rate range of from about 0.04sec⁻¹ to about 25 sec⁻¹. These vehicle systems are particularly usefulin hair care compositions, especially rinse-off hair conditioners. Mostpreferably, the hair care compositions formulated with these uniquevehicle systems comprise no more than about 1% of fatty alcoholmaterials.

DETAILED DESCRIPTION OF THE INVENTION

The essential as well as optional components of the present compositionsare described below.

Primary Thickener

The vehicle systems of the present invention contain, as an essentialcomponent, a primary thickening material. The primary thickeningmaterial is a hydrophobically modified nonionic water-soluble polymer.By "hydrophobically modified nonionic water-soluble polymer" is meant anonionic water-soluble polymer which has been modified by thesubstitution with a sufficient amount of hydrophobic groups to make thepolymer less soluble in water. Hence, the polymer backbone of theprimary thickener can be essentially any water-soluble polymer. Thehydrophobic groups can be C₈ to C₂₂ alkyl, aryl alkyl, alkyl aryl groupsand mixtures thereof. The degree of hydrophobic substitution on thepolymer backbone should be from about 0.10% to about 1.0%, depending onthe particular polymer backbone. More generally, the ratio ofhydrophilic portion to hydrophobic portion of the polymer is from about10:1 to about 1000:1.

A number of existing patents disclose nonionic polymer materials whichmeet the above requirements and which are useful in the presentinvention. U.S. Pat. No. 4,496,708, Dehm et al., issued Jan. 29, 1985,teaches water-soluble polyurethanes having hydrophilic polyetherbackbones and pendant monovalent hydrophobic groups to result in ahydrophilic/lipophilic balance of between about 14 and about 19.5. U.S.Pat. No. 4,426,485, Hoy et al., issued Jan. 17, 1984, discloses awater-soluble thermoplastic organic polymer having segments of bunchedmonovalent hydrophobic groups. U.S. Pat. No. 4,415,701, Bauer, issuedNov. 15, 1983, discloses copolymers containing a monoepoxide and adioxolane.

The most preferred primary thickener materials for use in the presentinvention are disclosed in U.S. Pat. No. 4,228,277, Landoll, issued Oct.14, 1980, which is incorporated herein by reference. The materialsdisclosed therein are thickeners comprising a nonionic long chainalkylated cellulose ether.

The cellulose ethers have a sufficient degree of nonionic substitutionselected from the group consisting of methyl, hydroxyethyl andhydroxypropyl to cause them to be water-soluble. The cellulose ethersare further substituted with a hydrocarbon radical having about 10 to 22carbon atoms in an amount between about b 0.2 weight percent and theamount which renders said cellulose ether less than 1%, by weight,soluble in water. The cellulose ether to be modified is preferably oneof low to medium molecular weight, i.e., less than about 800,000 andpreferably between about 20,000 and 700,000 (about 75 to 2500 D.P.)

The Landoll patent teaches that any nonionic water-soluble celluloseether can be employed as the cellulose ether substrate. Thus, e.g.,hydroxyethyl cellulose, hydroxypropyl cellulose, methyl cellulose,hydroxypropyl methyl cellulose, ethyl hydroxyethyl cellulose, and methylhydroxyethyl cellulose can all be modified. The amount of nonionicsubstituent such as methyl, hydroxyethyl or hydroxypropyl is taught notto be critical so long as there is an amount sufficient to assure thatthe ether is water-soluble.

The preferred cellulose ether substrate is hydroxyethyl cellulose (HEC)of about 50,000 to 700,000 molecular weight. Hydroxyethyl cellulose ofthis molecular weight level is the most hydrophilic of the materialscontemplated. It can thus be modified to a greater extend than can otherwater-soluble cellulose ether substrates before insolubility isachieved. Accordingly, control of the modification process and controlof the properties of the modified product can be more precise with thissubstrate. Hydrophilicity of the most commonly used nonionic celluloseethers varies in the general direction:hydroxyethyl→hydroxypropyl→hydroxypropylmethyl→methyl.

The long chain alkyl modifier can be attached to the cellulose ethersubstrate via an ether, ester or urethane linkage. The ether linkage ispreferred.

Although the materials taught in Landoll are referred to as being "longchain alkyl group modified", it will be recognized that except in thecase where modification is effected with an alkyl halide, the modifieris not a simple long chain alkyl group. The group is actually analphahydroxyalkyl radical in the case of an epoxide, a urethane radicalin the case of an isocyanate, or an acyl radical in the case of an acidor acyl chloride. Nonetheless, the terminology "long chain alkyl group"is used since the size and effect of the hydrocarbon portion of themodifying molecule completely obscure any noticeable effect from theconnecting group. Properties are not significantly different from thoseof the product modified with the simple long chain alkyl group.

Methods for making these modified cellulose ethers are taught in Landoll('277) at column 2, lines 36-65.

These materials have been found to be particularly desirable for use inthe vehicle systems of the cosmetic compositions of the presentinvention. The materials are able to stabilize suspensions of dispersedphases, and when used with the additional components in the vehiclesystems of the present invention, they produce rheologically thickproducts which lack the slimy feel characteristic of most polymericthickeners.

One commercially available material which meets these requirements isNATROSOL PLUS Grade 330, hydrophobically modified hydroxyethylcelluloseavailable from Aqualon Company, Wilmington, Del. This material has a C₁₆alkyl substitution of about 0.4% to about 0.8% by weight. Thehydroxyethyl molar substitution for this material is from about 3.0 toabout 3.7. The average molecular weight for the water-soluble celluloseprior to modification is approximately 300,000.

Another material of this type is sold under the trade name NATROSOL PLUSCS Grade D-67, by Aqualon Company, Wilmington, Del. This material has aC₁₆ alkyl substitution of from about 0.50% to about 0.95%, by weight.The hydroxyethyl molar substitution for this material is from about 2.3to about 3.3, and may be as high as about 3.7. The average molecularweight for the water-soluble cellulose prior to modification isapproximately 700,000.

The primary thickener component is present in the cosmetic compositionsof the present invention at from about 0.1% to about 10.0%, preferablyfrom about 0.2% to about 5.0%.

It is important that the primary thickener be well-hydrated anddispersed in the compositions of the present invention.

Water-Soluble Surfactant

The present vehicle systems further comprise, as a second essentialcomponent, a water-soluble surfactant having a molecular weight of lessthan about 20,000. By "water-soluble surfactant" is meant surfactantmaterials which form clear isotropic solutions when dissolved in waterat 0.2 weight percent at ambient conditions.

Nonlimiting examples of water-soluble surfactants which can be used inthe vehicle systems of the compositions of the present invention can beselected from water-soluble anionic, nonionic, cationic, zwitterionicand amphoteric surfactants.

Synthetic anionic surfactants include alkyl and alkyl ether sulfates.These materials have the respective formulae ROSO₃ M and RO(C₂ H₄ O)_(x)SO₃ M, wherein R is alkyl or alkenyl of from about 10 to about 20 carbonatoms, x if 1 to 10, and M is a water-soluble cation such as ammonium,sodium, potassium and triethanolamine. The alkyl ether sulfates usefulin the present invention are condensation products of ethylene oxide andmonohydric alcohols having from about 10 to about 20 carbon atoms.Preferably, R has from about 12 to about 18 carbon atoms in both thealkyl and alkyl ether sulfates. The alcohols can be derived from fats,e.g., coconut oil or tallow, or can be synthetic. Lauryl alcohol andstraight chain alcohols derived from coconut oil are preferred herein.Such alcohols are reacted with about 1 to about 10, and especially about3, molar proportions of ethylene oxide and the resulting mixture ofmolecular species, having, for example, an average of 3 moles ofethylene oxide per mole of alcohol, is sulfated and neutralized.

Specific examples of alkyl ether sulfates which can be used in thepresent invention are sodium coconut alkyl triethylene glycol ethersulfate; sodium tallow alkyl triethylene glycol ether sulfate; andsodium tallow alkyl hexaoxyethylene sulfate. Highly preferred alkylether sulfates are those comprising a mixture of individual compounds,said mixture having an average alkyl chain length of from about 12 toabout 16 carbon atoms and an average degree of ethoxylation of fromabout 1 to about 4 moles of ethylene oxide. Such a mixture alsocomprises from about 0 to about 20% by weight C₁₂₋₁₃ compounds; fromabout 60 to about 100% by weight of C₁₄₋₁₅₋₁₆ compounds, from about 0 toabout 20% by weight of C₁₇₋₁₈₋₁₉ compounds; from about 3 to about 30% byweight of compounds having a degree of ethoxylation of 0; from about 45to about 90% by weight of compounds having a degree of ethoxylation offrom about 1 to about 4; from about 10 to about 25% by weight ofcompounds having a degree of ethoxylation of from about 4 to about 8;and from about 0.1 to about 15% by weight of compounds having a degreeof ethoxylation greater than about 8.

Another suitable class of anionic surfactants are the water-solublesalts of the organic, sulfuric acid reaction products of the generalformula:

    R.sub.1 -SO.sub.3 -M

wherein R₁ is chosen from the group consisting of a straight or branchedchain, saturated aliphatic hydrocarbon radical having from about 8 toabout 24, preferably about 8 to about 14, carbon atoms; and M is acation. Important examples are the salts of an organic sulfuric acidreaction product of a hydrocarbon of the methane series, including iso-,neo-, ineso-, and n-parrafins, having about 8 to about 24 carbon atoms,preferably about 8 to about 14 carbon atoms and a sulfonating agent,e.g., SO₃, H₂ SO₄, oleum, obtained according to known sulfonationmethods, including bleaching and hydrolysis. Preferred are alkali metaland ammonium sulfonated C₁₂₋₁₈ n-paraffins.

Still other anionic synthetic surfactants include the class designatedas succinamates. This class includes such surface active agents asdisodium N-dodecylsulfosuccinamate; tetrasodiumN-(1,2-dicarboxyethyl)-N-dodecylsulfosuccinamate; diamyl ester of sodiumsulfosuccinic acid; dihexyl ester of sodium sulfosuccinic acid.

Other suitable anionic surfactants utilizable herein are olefinsulfonates having about 12 to about 24 carbon atoms. The term "olefinsulfonates" is used herein to means compounds which can be produced bythe sulfonation of α-olefins by means of uncomplexed sulfur trioxide,followed by neutralization of the acid reaction mixture in conditionssuch that any sultones which have been formed in the reaction arehydrolyzed to give the corresponding hydroxy-alkanesulfonates. Thesulfur trioxide can be liquid or gaseous, and is usually, but notnecessarily, diluted by inert diluents, for example by liquid SO₂,chlorinated hydrocarbons, etc., when used in the liquid form, or by air,nitrogen, gaseous SO₂, etc., when used in the gaseous form.

The α-olefins from which the olefin sulfonates are derived aremono-olefins having about 12 to about 24 carbon atoms, preferably about12 to about 16 carbon atoms. Preferably, they are straight chainolefins. Examples of suitable 1-olefins include 1-dodecene;1-tetradecene; and 1-hexadecene.

In addition to the true alkene sulfonates and a proportion ofhydroxy-alkanesulfonates, the olefin sulfonates can contain minoramounts of other materials, such as alkene disulfonates depending uponthe reaction conditions, proportion of reactants, the nature of thestarting olefins and impurities in the olefin stock and side reactionsduring the sulfonation process.

A specific α-olefin sulfonate mixture of the above type is describedmore fully in the U.S. Pat. No. 3,332,880, Pflaumer and Kessler, issuedJuly 25, 1967, incorporated herein by reference.

Another class of anionic organic surfactants are the β-alkyloxy alkanesulfonates. These compounds have the following formula: ##STR1## whereR₁ is a straight chain alkyl group having from about 6 to about 20carbon atoms, R₂ is a lower alkyl group having from about 1 (preferred)to about 3 carbon atoms, and M is a water-soluble cation as hereinbeforedescribed.

Many additional nonsoap synthetic anionic surfactants are described inMcCutcheon's, Detergents and Emulsifiers, 1984 Annual, published byAllured Publishing Corporation, which is incorporated herein byreference. Also U.S. Pat. No. 3,929,678, Laughlin et al., issued Dec.30, 1975, discloses many other anionic as well as other surfactant typesand is incorporated herein by reference.

Cationic amine surfactantsincluded among those useful int he present invention are disclosed inU.S. Pat. No. 4,275,055, Nachtigal, et al., issued June 23, 1981,incorporated by reference herein.

Zwitterionic surfactants are exemplified by those which can be broadlydescribed as derivative of aliphatic quaternary ammonium, phosphonium,and sulfonium compounds, in which the aliphatic radicals can be straightor branched chain, and wherein one of the aliphatic substituentscontains from about 8 to about 18 carbon atoms and one contains ananionic water-solubilizing group, e.g., carboxy, sulfonate, sulfate,phosphate, or phosphonate. A general formula for these compounds is:##STR5## wherein R² contain an alkyl, alkenyl, or hydroxy alkyl radicalof from about 8 to about 18 carbon atoms, from 0 to about 10 ethyleneoxide moieties and from 0 to about 1 glyceryl moiety; is selected fromthe group consisting of nitrogen, phosphorus, and sulfur atoms; R³ is analkyl or monohydroxyalkyl group containing about 1 to about 3 carbonatoms; X is 1 when is a sulfur atom, and 2 when is a nitrogen orphosphorus atom; R⁴ is an alkylene or hydroxyalkylene of from about 1 toabout 4 carbon atoms and Z is a radical selected from the groupconsisting of carboxylate, sulfonate, sulfate, phosphonate, andphosphate groups.

Other zwitterionics such as betaines are also useful in the presentinvention. Examples of betaines useful herein include the high alkylbetaines, such as coco dimethylcarboxymethyl betaine, lauryl dimethylcarboxymethyl betaine, lauryl dimethyl alphacarboxyethyl betaine, cetyldimethyl carboxymethyl betaine, lauryl bis-(2-hydroxyethyl)carboxymethyl betaine, stearyl bis-(2-hydroxypropyl) carboxymethylbetaine, oleyl dimethyl gammacarboxypropyl betaine, and laurylbis-(2-hydroxypropyl)alphacarboxyethyl betaine.

Examples of amphoteric surfactants which can be used in the vehiclesystems of the compositions of the present invention are those which arebroadly described as derivatives of aliphatic secondary and tertiaryamines in which the aliphatic radical can be straight or branched chainand wherein one of the aliphatic substituents contains from about 8 toabout 18 carbon atoms and one contains an anionic water solubilizinggroup, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate.Examples of compounds falling within this definition are sodium3-dodecylaminopropionate, sodium 3-dodecylaminopropane sulfonate,N-alkyltaurines such as the one prepared by reacting dodecylamine withsodium isethionate according to the teaching of U.S. Pat. No. 2,658,072,N-higher alkyl aspartic acids such as those produced according to theteaching of U.S. Pat. No. 2,438,091, and the products sold under thetrade name "Miranol" and described in U.S. Pat. No. 2,528,378.

Examples of particularly preferred water-soluble surfactant materialsfor use in the present vehicle systems are cetyl betaine, ammoniumlauryl sulfate, ammonium laureth sulfate, and cetyl trimethyl ammoniumchloride, and mixtures thereof.

The water-soluble surfactant is used with the primary thickener of thepresent invention at from about 0.02% to about 0.03%, preferably fromabout 0.05% to about 0.30%, most preferably from about 0.05% to about0.20%, of the composition. The water-soluble surfactant level is keptlow because higher levels of water-soluble surfactants interfere withthe primary thickener and produce compositions with much less desirablerheologies.

Solvent

A third essential component in the vehicle systems of the presentinvention is a solvent which is compatible with the other components inthe present compositions. Generally the solvent will comprise water or awater-lower alkanol mixture. The solvent is present in the compositionsof the present invention at a level of from about 65% to about 99% byweight of the cosmetic composition.

The other components are dispersed or mixed in the solvent to provide anoptimum thick rheology to the cosmetic compositions formulated therewithwhich mimics the gel-network rheology of typical hair conditioningcompositions. This rheology is characterized by a shear stress of from 0to about 50 pascal, over a shear rate range of 0.04 sec⁻¹ to 25 sec⁻¹.The rheology is measured using a Bohlin Rheometer VOR with the followingcone and plate set-up: cone has a 2.5 degree angle, plate is 30 mm indiameter, the gap between the truncated cone and plate is set at 70 μm,and the toque bar used is 20.148 g-cm. The sample amount is 0.35 ml andthe sample is syringed onto the center of the plate. The system used isas follows: there is no initial delay time, the strain delay time is 25sec, the integration time is 5 sec, the sensitivity is set at 1 X, theshear sweep is up, the shear range is from about 0.0405 sec⁻¹ to 25.53sec⁻¹ (shear No.=11 to 39), and the temperature is maintained constantbetween series at ambient temperature (20° C. to 25° C.).

Additional Thickener

The present vehicle systems can also comprise an additional thickeningcomponent, which comprises a water-soluble polymeric material, having amolecular weight greater than about 20,000 . By "water-soluble polymer"is meant that the material will form substantially a clear solution inwater at a 1% concentration at 25° C. and the material will increase theviscosity of the water. Examples of water-soluble polymers which maydesirably be used as an additional thickening component in the presentvehicle systems, are hydroxyethylcellulose, hydroxypropyl cellulose,hydroxypropyl methylcellulose, polyethylene glycol, polyacrylamide,polyacrylic acid, polyvinyl alcohol, polyvinyl pyrrolidone K-120,dextrans, for example, Dextran purified crude Grade 2P, available fromD&O Chemicals, carboxymethylcellulose, plant exudates such as acacia,ghatti, and tragacanth, seaweed extracts such as sodium alginate,propylene glycol alginate and sodium carrageenan, and Ucare JR-polymer(a cationic modified hydroxyethyl cellulose available from UnionCarbide). preferred as the optional additional thickener for the presentvehicle systems are natural polysaccharide materials. Examples of suchmaterials are guar gum, locust bean gum, and xanthan gum. Also preferredas the additional thickener in the present compositions is hydroxyethylcellulose, having a molecular weight of about 700,000. It is importantthat these polymer materials not contain cellulose as this may interferewith obtaining optimum product viscosities.

The additional thickening component, if present in the cosmeticcompositions of the present invention, is at a level of from about 0.3%to about 5.0%, preferably from about 0.4% to about 3.0%.

It is important that these additional polymer materials be well-hydratedand dispersed in the present compositions.

Rheological Aid

The vehicle systems of the present invention preferably also contain amaterial which provides additional rheological benefits to the cosmeticcompositions formulated therewith. These materials are chelating agents.In general, such materials include monodentate and multidentate agents.Specific examples of useful chelating agents includeethylenediaminetetraacetic acid (EDTA), and salts thereof, nitriloaceticacid (NTA) and salts thereof, hydroxyethyl ethylene diamine triaceticacid (EEDTA) and salts thereof, diethylene triamine pentaacetic acid(DTPA) and salts thereof, diethanolglycine (DEG) and salts thereof,ethanol diglycine (EDG) and salts thereof, citric acid and saltsthereof, phosphoric acid and salts thereof. The most preferred of theseis EDTA. The chelating agents tend to make the vehicle systems of thepresent invention smoother and less gelatinous in consistency.

If a chelating agent is present as a rheological aid in the compositionsof the present invention it is present at a level of from about 0.05% toabout 1.0%, preferably from about 0.05% to about 0.3%, of thecomposition.

Distributing Aid

An additional component in the vehicle systems of the present inventionis a material which acts as a distributing aid for the composition. Sucha material helps to distribute the cosmetic composition onto the hair orskin avoiding localized deposition of the active component onto the hairor skin. Without such a component in a composition, some activecomponents in the composition would not be deposited and spread out asevenly, and hence, would not be quite as effective.

Distributing aid materials useful in the present invention are actuallya subclass of the class of materials used as the optional water-solublepolymer additional thickener in the present invention. This subclass isdefined as follows: water-soluble polymer materials having highmolecular weight, i.e., greater than 1,000,000; and/or strong ioniccharacter. By strong ionic character is means that the material conductselectricity at greater than 30 millivolts. This can be measured byevaluating conductance of a 1% solution of polymer in DRO (doublereverse osmosis) water preserved with 0.03% Kathon CG (a preservativeavailable from Rohm & Haas) using a calibrated Corning 130 p meter. Theprobes used are as follows. The reference electrode is an Orion Model9001 single junction. The p electrode is an Orion Model 9161,silver-silver chloride. The probes are set 3/8 of an inch apart. The pmeter is set to millivolt readings. The absolute measurement is recordedafter 4 minutes immersion.

Examples of water-soluble polymer materials which meet theserequirements and hence, can act as distributing aids in the presentcompositions, include xanthan gum; Dextran purified crude Grade 2P,available from DO Chemicals; carboxymethyl celluloses; for example,CMC's 4H1F, 4M6F, 7HF, 7M8SF, 7LF, 9H4F, 9M8, 12M8P, 16M31 (allavailable from Aqualon); plant exudates such as acacia, ghatti andtragacanth; seaweed extracts such as sodium alginate, propylene glycolalginate, and sodium carrageenan; high molecular weighthydroxyethylcelluloses, such as Natrosol 250 H and Natrosol 250 R(available from Aqualon); and pectin.

Because the class of materials which may act as distributing aids in thepresent invention is a subset of the optional water-soluble polymeradditional thickener, the materials in this subclass may be used toprovide both benefits to the composition. For example, xanthan gum is awater-soluble natural polysaccharide material which additionally has ahigh molecular weight. Hence, this material could be used by itself toprovide both additional thickening benefits and distributing benefits.However it may be necessary to use such materials at slightly higherlevels to provide both benefits.

It is also possible to use two separate materials as the optionalwater-soluble polymer additional thickener and the distributing aid ofthe present invention. This would be done when the water-soluble polymeradditional thickener was not a high molecular weight material or ofstrong ionic character. Locust bean gum is such a material. Adistributing aid such as xanthan gum could be used with locust bean gumto provide the additional distributing benefits.

If a distributing aid is present in the cosmetic compositions of thepresent invention, it should be present at a level of from about 0.02%to about 2.5%, preferably from about 0.05% to about 1.0%, of thecosmetic composition. If the distributing aid is bifunctional, i.e.,acting as both the optional additional thickener and the distributingaid it should be present at a level of from about 0.2% to about 5.0% ofthe composition.

A distributing aid is particularly useful in hair care compositions ofthe present invention, especially rinse-off hair conditioners. Thedistributing aid helps to spread same hair conditioning componentsevenly over the hair.

The present vehicle systems and cosmetic compositions formulatedtherewith must comprise no more than about 1%, preferably no more thanabout 0.5%, total of water-soluble surfactant materials. High levels ofthese materials are not compatible with the vehicle systems of thepresent composition. High levels of these materials destroy the uniquedesirable rheology that is the object of the present invention. Examplesof specific water-soluble surfactant materials that can be particularlyharmful to the present vehicle systems at high levels are alkyl sulfatesand ethoxylated alkyl sulfates, such as ammonium lauryl sulfate;amphoteric surfactants which are derivatives of aliphatic secondary andtertiary amines; nonionic surfactants produced by the condensation ofalkylene oxide groups with an organic hydrophilic compound, such aslaureth-23 (sold under the trademark Brij 35 by ICI Americas); and highalyl betaines, sulfo betaines, amido betaines and amido sulfobetaines,such as cetyl betaine. Such materials are commonly used in hair shampoocompositions.

The present vehicle systems and cosmetic compositions formulatedtherewith are also preferably substantially free of fatty alcoholmaterials, such as stearyl-, cetyl-, myristyl-, behenyl-, lauryl-, andoleyl alcohols. By "substantially free of fatty alcohol materials" ismeant that the compositions of the present invention comprise no morethan about 1% of these materials. These materials are commonly used invehicle systems for hair conditioner products. However, these materialsare undesirable because they tend to deposit on the hair and leave thehair feeling dirty after use. These materials are not required and arenot desirable in the present vehicle systems, as they are thickened withalternative materials which do not deposit on hair.

The present vehicle systems can be used in essentially any cosmeticproducts having a thick gel-network type rheology and which are used todeliver some active component onto the hair or skin. Such compositionswould include skin moisturizing lotions, sunscreen compositions, andskin cleansing compositions. However, cosmetic compositions mostdesirably used with the present vehicle systems are hair care products,especially rinse-off hair care products where some active hair carecomponent is to be deposited onto the hair but the vehicle carrying thatcomponent is desirably rinsed off the hair with little or not depositionof the vehicle material onto the hair.

Generally, the present vehicle systems will not be useful in typicalshampoo compositions since these compositions contain high levels ofwater-soluble surfactants, which, as discussed supra, are incompatiblewith the present vehicle systems. However, the present vehicle systemsare useful in typical hair coloring compositions, hair tonic or gelcompositions, hair mousse compositions, and especially hair conditioningcompositions.

Active Cosmetic Component

Preferred polymers comprise a vinyl polymeric backbone having a Tg or aTm above about -20° C. and, grafted to the backbone, apolydimethylsiloxane macromer having a weight average molecular weightof from about 1,000 to about 50,000, preferably from about 5,000 toabout 40,000, most preferably about 20,000. The polymer is such thatwhen it is formulated into the finished hair care composition, whendried, the polymer phase separates into a discontinuous phase whichincludes the polydimethylsiloxane macromer and a continuous phase whichincludes the backbone. It is believed that this phase separationproperty provides a specific orientation of the polymer on hair whichresults in the desired hair conditioning and setting benefits.

The particle size of the copolymer material of the present compositionsmay have some effect on performance in product. This, of course, willvary from copolymer to copolymer and from product to product.

The copolymers are preferably combined with a solvent for the copolymerprior to combination with the vehicle systems of the present invention.

The solvent selected must be able to dissolve or disperse the particularsilicone copolymer being used. The nature and proportion of B monomer inthe copolymer largely determines its polarity and solubilitycharacteristics. The silicone copolymers can be designed, by appropriatecombination of monomers, for formulation with a wide range of solvents.Suitable solvents for use in the present invention include, but are notlimited to, water, lower alcohols (such as ethanol, isopropanol),hydroalcoholic mixtures, hydrocarbons (such as isobutane, hexane,decene, acetone), halogenated hydrocarbons (*such as Freon), linalool,hydrocarbon esters (such as ethyl acetate, dibutyl phthalate), volatilesilicon derivatives, especially siloxanes (such as phenyl pentamethyldisiloxane, phenethyl pentamethyl disiloxane, methoxypropyl heptamethylcyclotetrasiloxane, chloropropyl pentamethyl disiloxane, hydroxypropylpentamethyl disiloxane, octamethyl cyclotetrasiloxane, decamethylcyclopentasiloxane), and mixtures thereof. Preferred solvents includewater, ethanol, volatile silicon derivatives, and mixtures thereof.

The unique vehicle systems of the present invention provide superiorperformance vis a vis delivery of the active cosmetic component to thehair or skin. This is especially true in the case of hair carecompositions. Lower levels of active components may be used in the haircare compositions of the present invention than are used in hair carecompositions formulated with alternative thickening systems. Thesedeposition benefits are especially noticeable in the case of siliconehair conditioning agents. The quantity and quality of silicone depositfrom the present unique vehicle systems on hair results in enhanced hairconditioning.

These active cosmetic care materials are generally present at a level offrom 0% to about 20%, preferably from about 0.1% to about 20%, by weightof the cosmetic composition. The 0% level reflects the situation whenone of the vehicle components provides the hair care activity to thepresent compositions. For example, if the vehicle system comprises awater-soluble quaternary ammonium compound, this material will providehair conditioning benefits as well. The level of the active cosmeticcare material varies depending upon which active material is chosen, theparticular cosmetic compositions to be formulated therewith, and thelevel of benefit desired.

Other optional components that can be added to the cosmetic compositionsof the present invention do not provide any direct cosmetic care benefitbut instead enhance the composition in some way. Examples of suchmaterials are coloring agents, such as any of the FDC or DC dyes;opacifiers, pearlescent aids, such as ethylene glycol distearate or TiO2coated mica; pH modifiers, such as citric acid, succinic acid,phosphoric acid, sodium hydroxide, and sodium carbonate; preservatives,such as benzyl alcohol, ethyl paraben, propyl paraben, andimidazolidonyl urea; and antioxidants. Such agents generally are usedindividually at a level of from about 0.001% to about 10%, preferablyfrom about 0.01% to about 5%, of the hair care composition.

The vehicle systems and cosmetic compositions of the present inventioncan be made using conventional formulation and mixing techniques.Methods of making various types of cosmetic compositions are describedmore specifically in the following examples.

The following examples illustrate the present invention. It will beappreciated that other modifications of the present invention within theskill of those in the cosmetic composition formulation art can beundertaken without departing from the spirit and scope of thisinvention.

All parts, percentages, and ratios herein are by weight unless otherwisespecified.
